T0 all 'wh-0m t may conce-m Be it known that I, `EARL a citizen Vof -the United States, residing at Culver City, 'in the county of'Los Angeles aand State of California, have invented a new and useful Blow- Out Patch, o'f which The material is notched 'out between the the following is aspecification. My object isto make a blow-out patch which will."securely'inclose the inner tube 1o and limitthe expansion of the inner tube at the point covered byfthe patch and which Vwill not creep 1n shown, described and claimed.

Figure 1 is a fragmentary longitudinal sectional detail showing my blow-out patch in position around the inner tube and-within the outer casing, the view being taken on the line 1-.1 of Fig. 2. Fig. 2 is a cross' sec- 20 noun dean on the une a-a of Fig. 1.A Fig.

`3 is a fragmentary cross section showing the details of thepatch, the casing and inner tube being omitted, as taken on the line 3"8 of Fig. 1. Fig. l isa View in elevation of 2 5 the patch, looking in thefdirection indicated by the arrow 4 in Fig. 3, asfthepatch would be seen looking from Fig. 5- is a view analogous to Fig. 4: and showing two hinge pins, whereas in Fig.l l used, as indicated by the arrowv in Fig. 6. Fig. 6 is a fragmentary cross section analogous to Fig."3 and taken on the line 6`-6 `of Fig. 5. Fig. "Z is a view analogous to Figs.` 4 and 6 with the 35 hinge pins omitted.

The blow-out patch 1 embodying the principles of my invention is clamped around the inner tube 2 .se as to limitthe expansion of the inner tube l.ndis placed within the 40 outer 'casing 3. at a point to make an inside cover for the blow-outhole, such as 4. x

The details of the blow-out patch 1 are as lfollowsrln Figs. 2,3 and 6s have shown tbe patch4 constructed of three layers,

6 and 7, and it is to `be understood that any desired number of layers may be used and the material really employed is the same as or similar used. in building up the outer casing and that is rubberized fabric'or canvas which,

when placed together, will vulcanize to'- gether. i The'inner section 1 is cutto the de patch and wide enough H. MoREHoUsE,

the casing; and my invention consists of the novel features herein line as in Fig.

V12 and to the' materialto reach around the inner casing rand to form the inter-meshing bearings 8 and -9.

The bearings 8 upon one side of the section g vare staggered relativev to the bearings 9 upon the opposite .slide of the section, so thatthe bearings w1ll inter-mesh, as in a door hinge.

bearings,pthus forming tongues 10 and 11 which are wrapped around and wired to the desired size landfolded back upon the body i of the material and applied to the outer face of the section L1 and overlapping the tongues 10 and 11. Then the section 7 is cut to the `desired length to cover the section 6 and,

rim, so as to leave `the outer edges of the thus constructed is flaps free. .The patch placed around theinner tube 2 at` the desired point and the bearingsbrought into 4 andthe hinge pin 15 inserted, thereby making a secure clamp around ythe linner casing to limit its eXpansion. If the patch is slightly larger than required for the tire to which it is to be applied, the 'bearings' may as in`Figs.,5 .ando and two hinge pinss16 and 17 applied. The hinge pins 15, .16 and 17 are outside of suiicient material to protect the'inner ltube from being abrad'ed or punctured. The hinge pins may have bent ends for heads, as shown, or

any other. desired form of head. The flaps 3 and the rim 14 and will prevent the patch from creeping in the casing and these fiaps serve as handles for pulling the inner tubev andpatch out of the casing, when desired.

The details of construction may be varied spirit of rnvinvention, as set up in the following claims. v v
